RESM for MCAS Yuma

GBE is developing a Real Estate Summary Map (RESM) for Marine Corps Air Station (MCAS)Yuma. GBE is providing overall supervision of the boundary inventory portion for this assignment that includes development of a RESM for the air base and all outlying properties managed by MCAS Yuma. It includes all research of Muniments and Public Records, tabulation of in-grant and out-grants and all graphic representation. A Record of Survey was developed for the Martinez Lake Recreation Area to resolve numerous discrepancies with the legal boundary and lease agreements originally issued by the Bureau of Land Management and currently managed by the State Land Department. The living document database that was developed included active links between tabular data and the graphic map.

Perrin Ranch Wind Energy Project

GBE provided professional surveying services for this wind energy center that is made-up of 81 GE 1.6 MW wind turbines located on 40,000 acres of ranch land is located approximately 20 miles north of Williams, Arizona. GBE developed all documentation for Private and State Lease acquisitions and performed an ALTA survey for the entire project that covered the 40,000 acres. The effort included a cadastral land survey retracement of an area larger than two townships. GBE developed construction exhibits for 40 miles of corridors using LiDAR imagery as a backdrop to provide the contractor an existing footprint to identify various topographic and cultural impacts.

YCFCD On-Call Services

Working in an advisory role to the Yavapai County Flood Control District (YCFCD) as part of ongoing annual on-call contracts, GBE acts as lead surveyor in the performance of floodplain cross section surveys to determine impacts to individual private property owners. GBE is also the surveyor in charge of District mapping and control densification for FEMA Map Modernization efforts to determine elevations for floodplain properties and geodetic spatial reference networks. GBE has expanded the original county control network that was established in the 1980’s to include most of the now developed portions of Yavapai County. Aerial mapping efforts have included over 500 square miles of Yavapai County.

Yavapai Ranch Wind Energy Project

GBE is providing professional surveying services for this solar under wind energy center made-up of 62 GE 1.6 MW wind turbines and 200 acres of PV solar panels located on 51,000 acres of ranch land approximately 15 miles south of Seligman, Arizona. The Micrositing process included navigation to all turbine locations including 19 alternate locations. Preliminary investigation of corridors for access and collection systems is performed by physical navigation of accessible routes to the tops of the mesa’s where the turbine is located. GBE also developed CAD line work for proposed route changes as well as the inventory of all existing ranch water infrastructure facilities.

Chino Valley Center Street Improvements

GBE provided construction survey services for this 1 mile roadway rehabilitation project. The work consisted of layout of design plans for a rural roadway that was to receive an urban section including sidewalks and curb and gutter. The project also included a connection to ADOT Highway 89 with modification to the signalized intersection. Perpetuation of existing utility features in order to preserve their location for post construction treatment was also a part of the scope of work.

Crossroads Solar Project

GBE provided professional services on this solar energy center consisting of 4000 acres of farm land north of Interstate 8 at the Painted Rock Dam Road Interchange. GBE developed the ALTA/ACSM land title survey for the owner as part of their financing due diligence process. GBE utilized LiDAR imagery and aerial planimetric data for ground truthing of existing features. The Cadastral portion of this project was a retracement of the Maricopa County GDACS along with verification of existing PLSS survey work.

Groom Creek Water District Improvements

GBE provided construction staking and layout for the installation of over 20,000 lineal feet of domestic water line. Built in the 1970’s the existing mountain area required GBE to evaluate all of the existing plats to determine rights of way for the new lines as well as to determine the locations of all existing lines. Topographic mapping was developed for use in the engineering design. Once under construction, GBE provided layout information for all features including fire hydrants and water meters in addition to the main lines and well site.
